Inspection should be carried out with rope electrostatic ring and static finger cover (both hands except small fingers must be worn) YU DU AMSON ELECTRONICS CO.,LTD. Page 17 of 23
11.2.6. The inspector may make a visual inspection or a comparative examination with a film ruler and a magnifying eyepiece. Individual defects shall be determined according to the limited samples. 11.2.7. Functional testing uses electrical testing fixtures or test fixtures required by customers. 11.2.8. the ion fan should be used when testing. 11.2.9. the principle of judgment 11.3.1 If the defect outside the visual area does not affect the assembly and display, it will be judged as a good product. 11.3.2 Poor definition Pixel: A combination of three sub-pixels (Red + Green + Blue). Dot: Any of the sub-pixels (Red or Green or Blue). Bright and dark dots: A point pixel (sub-pixel: R, G, B pixels) is lit or turned off during the display function test. Highlights: Usually considered to be shown on a black screen. Dark spots: They are generally considered to be shown on R, G, B solid colors or white images. Neighborhood: Two or three adjacent point pixels (dot: sub-pixel) connected together (R, G or G, B or B, R or RGB). YU DU AMSON ELECTRONICS CO.,LTD. Page 18 of 23

12. Handling Precautions 12.1 Mounting method The LCD panel of AMSON TFT module consists of two thin glass plates with polarizes which easily be damaged. And since the module in so constructed as to be fixed by utilizing fitting holes in the printed circuit board. Extreme care should be needed when handling the LCD modules. 12.2 Caution of LCD handling and cleaning When cleaning the display surface, Use soft cloth with solvent [Recommended below] and wipe lightly Isopropyl alcohol Ethyl alcohol Do not wipe the display surface with dry or hard materials that will damage the polarizer surface. Do not use the following solvent: Water Aromatics Do not wipe ITO pad area with the dry or hard materials that will damage the ITO patterns Do not use the following solvent on the pad or prevent it from being contaminated: Soldering flux Chlorine (Cl), Sulfur (S) If goods were sent without being sili8con coated on the pad, ITO patterns could be damaged due to the corrosion as time goes on. If ITO corrosion happen by miss-handling or using some materials such as Chlorine (CI), Sulfur (S) from customer, Responsibility is on customer. 12.3 Caution against static charge The LCD module use C-MOS LSI drivers, so we recommended that you: Connect any unused input terminal to VDDIO or GND, do not input any signals before power is turned on, and ground your body, work/assembly areas, and assembly equipment to protect against static electricity. 12.4 packing Module employs LCD elements and must be treated as such. Avoid intense shock and falls from a height. To prevent modules from degradation, do not operate or store them exposed direct to sunshine or high temperature/humidity 12.5 Caution for operation It is an indispensable condition to drive LCD s within the specified voltage limit since the higher voltage then the limit cause the shorter LCD life. An electrochemical reaction due to direct current causes LCD s undesirable deterioration, so that the use of direct current drive should be avoided. Response time will be extremely delayed at lower temperature then the operating temperature range and on the other hand at higher temperature LCD s how dark color in them. However those phenomena do not mean malfunction or out of order with LCD s, which will come back in the specified operation temperature. If the display area is pushed hard during operation, some font will be abnormally displayed but it resumes normal condition after turning off once. Slight dew depositing on terminals is a cause for electro-chemical reaction resulting in terminal open circuit. Usage under the maximum operating temperature, 50%Rh or less is required.

12.6 storing In the case of storing for a long period of time for instance, for years for the purpose or replacement use, the following ways are recommended. Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it. And with no desiccant. Placing in a dark place where neither exposure to direct sunlight nor light s keeping the storage temperature range. Storing with no touch on polarizer surface by the anything else. [It is recommended to store them as they have been contained in the inner container at the time of delivery from us. 12.7 Safety It is recommendable to crash damaged or unnecessary LCD s into pieces and wash off liquid crystal by either of solvents such as acetone and ethanol, which should be burned up later. When any liquid leaked out of a damaged glass cell comes in contact with your hands, please wash it off well with soap and water. 13. Precaution for Use 13.1 A limit sample should be provided by the both parties on an occasion when the both parties agreed its necessity. Judgment by a limit sample shall take effect after the limit sample has been established and confirmed by the both parties. 13.2 On the following occasions, the handing of problem should be decided through discussion and agreement between responsible of the both parties. When a question is arisen in this specification. When a new problem is arisen this is not specified in this specification. When an inspection specifications change or operating condition change in customer is reported to AMSON TFT and some problem is arisen in this specification due to the change. When a new problem is arisen at the customer s operating set for sample evaluation in the customer site. 14. Packing Method TBD YU DU AMSON ELECTRONICS CO.,LTD. Page 23 of 23
